Chris Pratt Saves the Day in ‘Jurassic World’s’ First Full Trailer (Video)

Bryce Dallas Howard co-stars as the dino-making scientist who doesn’t know any better

Jurassic World has finally opened for business.

Universal Pictures and Legendary dropped the first full-length, dino-filled trailer for “Jurassic World” on Tuesday, the fourth film in the Steven Spielberg-created “Jurassic Park” franchise. Directed by Colin Tervorrow and starring Bryce Dallas Howard and Chris Pratt, this installment focuses on a world where the park is finally taking visitors.

“We have learned more in the past decade from genetics than a century of digging up bones,” Howard says. “A whole new frontier has opened up, we have our first genetically modified hybrid.”

Uh-oh. It sounds like scientists the are playing God again — that rarely ends well.

Pratt concurs. Fresh off guarding the galaxy for Marvel, the “Parks and Recreation” comedian-turned-action star is saving thousands of park visitors who clearly weren’t scared off by the 1993 original.

“You just went and made a new dinosaur?” he asks Howard. “Probably not a good idea.”

Boy is he right. Soon the trailer greets us with the sounds of screaming children and images of freshly cleaned bones, likely the work of our hybrid dinosaur.

“She’s a highly intelligent animal,” Pratt explains. “She will kill anything that moves.”

“Jurassic World” roars into theaters on June 12, 2015. Watch the trailer.
